What is Trusted Cofounder?

Trusted Cofounder is a public directory of founders and cofounders in Finland. Each person's profile includes a free-text description of what they want to build or join. Browsing is free; you only sign up when you want to message someone.

How do I find a cofounder in Finland?

Open the public directory at trustedcofounder.com/talent, filter by city, role, or skill, and click any profile to read their description. When you find someone you want to talk to, sign up once to send a message. We never expose email or contact details until both sides accept the connection.

Yes. Browsing the directory and reading public profiles is free without an account. Signing up to message is also free. There are no monetised tiers during this stage of the product.

Are profiles public or private?

Profiles are public by default and show the person's real name and photo. Anyone who prefers to stay private can hide their name and photo, and their card then shows role, city, description excerpt, and top skills only. Email and contact details are never shown on the public surface. Browsing is free and needs no signup.
